“It’s beyond language.” So speaks ex-clergyman Christopher Roulston in Observe the Sons of Ulster Marching Towards the Somme. For McGuinness, the limitations of language are both restriction and liberation, something to be railed against as much as it is to be manipulated.

“The house has grown cold, the province has grown lonely…The temple of the Lord is ransacked…Dance in this deserted temple of the Lord.”

As the whistle blew in Thiepval wood at 7:30 am on 1st July 1916, the men of the 36th (Ulster) Division began their march in to no-man’s land under a hail of German bullets. Today, their ghosts are still marching on banners and on gable walls throughout Northern Ireland.

In AA meetings, we are urged to “look for the similarities not the differences”. Watching People, Places, Things, I didn’t need to look hard, the parallels between my own life and the story onstage were obvious

It is now one hundred years since drugs were first banned -- and all through this long century of waging war on drugs, we have been told a story about addiction by our teachers and by our governments. This story is so deeply ingrained in our minds that we take it for granted. It seems obvious. It seems manifestly true. Until I set off three and a half years ago on a 30,000-mile journey for my new book, Chasing The Scream: The First And Last Days of the War on Drugs, to figure out what is really driving the drug war, I believed it too.
